Aniline detection dedicated chromatograph

Aniline is the most importantamineOne of the class substances. Mainly used for manufacturingdye、drug、resinIt can also be used asRubber vulcanizationPromoters, etc. It can also be used as a black dye itself. Its derivativesmethyl orangeCan be used as an indicator for acid-base titration.

Has alkalinity, can react with hydrochloric acid to form hydrochloride salt, and synthesize with sulfuric acidsulfateCan cause halogenationAcetylation、diazotizationWaiting for action. When exposed to open flames or high heat, it is flammable and the burning flames will produce smoke.. Compared to acids, halogensalcoholsAmines undergo strong reactions and can cause combustion.

Under the conditions of 200-210 ℃ and 5.86-6.55 megapascals, using cuprous chloride as a catalyst, chlorobenzene reacts with ammonia to produce aniline, with a one-way conversion rate of about 50-60% and a total yield of about 96%

Aniline is one of the most important intermediates in the dye industry, which can be used to manufacture acidic ink blue G, acidic medium BS, acidic pale yellow, direct orange S, direct peach red, indigo, dispersed yellow brown, cationic peach red FG, and reactive brilliant red X-SB; In the field of organic pigments, it is used to manufacture golden red, golden red g, red powder, phenol red, oil soluble black, etc. Used in the printing and dyeing industry for the dye aniline black; Used in the pesticide industry to produce many insecticides, fungicides such as DDV, herbicides, and herbicides; Aniline is an important raw material for rubber additives, used in the manufacture of anti-aging agents A, D, RD, 4010, M, 808, D, and CA, among others; It can also be used as a raw material for pharmaceutical sulfonamide drugs, as well as an intermediate in the production of fragrances, plastics, varnishes, films, etc.

Aniline is an important raw material for the production of pesticides, from which N-alkylaniline, alkylaniline, ortho nitroaniline, cyclohexylamine, etc. can be derived. It can be used as an intermediate for fungicides such as sodium dichlorvos, seed mix, insecticides such as triazophos, pyridazine, and quinthion, herbicides such as metoclopramide, cyclohexanone, and imidazolidinoic acid.
